In my experiance when dealing with disperate groups of layers, having an
override that will always work(ala old _local) was useful for helping
others do custom work. Its obviously something you really wouldn't want
stuck in to any actual provided meta data, but the end user should be
able to always be able to shoot them selves in the foot, if they really
really want to.

OTOH leaving it it up to the distro's to add back in is fine.
